Answer Posted / jayesh pakhale
Because Inputs of the opamp go to the base of the
transistors where transistors are in CE mode which provide
high base to emitter resistance while low collector to
emitter resistance so the input resistance of opamp is high
while ouput resistance of opamp is low which are required
to work opamp as a amplifier.
